It's hard to beat the value proposition of Google's Chromecast. For just $35, the itty-bitty TV dongle turns any dumb TV into a smart TV chock full of apps like Netflix, YouTube, HBO Go, Hulu Plus, Aereo, Rdio, Plex, and more. That's an awful lot to bring to the living room—but a new feature that's quietly rolled out to Chromecast gives the dongle a role in school rooms and offices, too.

As first noticed by Android Police, Google Drive presentations can now be sent to Chromecast from your PC, assuming you have the Google Cast extension installed in your Chrome browser. Assuming you do, slinging that slideshow to your big-screen is as easy as clicking on Present > Present on another device > [Chromecast name].

The mobile versions of Drive don't support casting yet, but the addition of presentation casting buoys both the Chromecast itself as well as Google's burgeoning Chromebook endeavor. Chromebooks, remember, are seeing the most traction in schools and businesses, and adding a low-cost presentation accessory to the mix only makes them more enticing in those scenarios.
